[2019-09-30] Квантовое самоубийство — Википедия [[quantum]]

Риск того, что в результате эксперимента ружьё выстрелит и участник умрёт, составляет 50 %. Если копенгагенская интерпретация верна, то ружьё в конечном итоге выстрелит, и участник умрёт.
Если же верна многомировая интерпретация Эверетта, то в результате каждого проведенного эксперимента вселенная расщепляется на две вселенных, в одной из которых участник остается жив, а в другой погибает.
В мирах, где участник умирает, он перестает существовать. Напротив, с точки зрения неумершего участника, эксперимент будет продолжаться, не приводя к исчезновению участника.
Это происходит потому, что в любом ответвлении участник способен наблюдать результат эксперимента лишь в том мире, в котором он выживает. И если многомировая интерпретация верна, то участник может заметить, что он никогда не погибнет в ходе эксперимента.

[2019-12-28] Simulating physical reality with a quantum computer | Lobsters

Asiking since I feel like this particular example doesn’t answer yet “why bother using quantum computing for that”? In essence, here we just multiply initial state by the evolution matrix, which is a trivial task for classical computers (when the size isn’t exponential).
For instance, when justifying use for Shor’s or Grover’s algorithm it’s easy to understand the speedup since the problems are fairly abstract and it’s clear how compexity grows with size. Wonder if in a similar manner, it’s possible to come up with some made-up system of N electrons (or other particles, if it would make Hamiltonian simpler/closer to reality), that would be relatively easy to solve analytically (or just reason about qualitatevely), but straighforward construction of Hamiltonian matrix would be infeasible? And then once could map the Hamiltonian onto quantum gates and that demonstrate that the results predicated by quantum computer match the analytical solution.

    @karlicoss I think this talk is highly relevant: especially the part about digital substrates. I think we have the same issue as soon as we step outside the browser, and it's a fundamental problem in the way we have imagined interfaces should be created, distributed and used.
For desktop apps check out this paper by my friend James

[2020-04-28] Riot | Malleable Systems Collective

Re: “macroscopic” properties, this seems to me to be closely related to a concept in the natural sciences call “renormalization group flow”, and possibly some ideas from cybernetics.
One could imagine the space of states “flowing” through an app, and the macroscopic ones are those which are the most stable under perturbations (and therefore most ideal for getting strong understanding and building structure on top of). IMHO, the problem with conventional CS is how much it’s digital i.e. conditionals and cases and expects exact states, whereas good systems (to model the real world) might look much more analog in how they can marshal a variety of states into a set of well-defined ones.

Two cases: there is greater mind that will stop nature from falling apart. Two cases: we intervene or we're not

It there is no: we're at risk of nature and us extincting if we don't do anything.

Mycroft AI uses two intent parsers. The first, Adapt, uses a keyword-matching approach to determine a confidence score, then passes control to the skill, or command, with the highest confidence. Padatious takes a different approach, where examples of entities are provided so it can learn to recognize an entity within an utterance.

Federated timeline thoughts [[mastodon]]

Users weighted by presence in federated timeline
Stats on toot likes/mutes

problem: assembling data from API

api allows retrieving messages before certain timestamp, from newer to older
can you prove that it's not possible to assemble data in some memory efficient and consistent way?

e.g. if we had oldest to newest, it'd be possible to 'extend' both ways, thus persisting middle bit
with one way we have to keep track of and merge 'segments'

binary search? E.g. artificially make 'oldest to newest' by reverting query results

another approach

say messages go from A …. Z – oldest to newest'
fetch: K — P ; interrupted
so you've got some middle chunk.
you can extend left bit committing regularly
e.g. G - K => G — P
B - G => B – P

Right bit, however, is more trickly. You'll always have to commit in a single transaction

Otherwise you might end with a gap after P you'll never close

It's actually ok if you run often enough. But if you don't run for a year and want to carry on, it's gonna be quite annoying.

I guess one option is –refresh mode? go from the very end, ignore beginning and just fill it

some thoughts on before= API vs after= API [[api]] [[social]] [[exports]]

I'd never imagine I'd be coming up with theoretical puzzles involving APIs… but here I am.

Say you've got an API serving messages (say, <= 10 at a time) from newest to oldest.

In addition you've got optional 'before' parameter:

Now imagine you want to persist all messages in the database and TODO properties

If API was different (TODO maybe even mentioning newet to oldest isn't important). can always sort.

allows for fairly easy

[oldest … newest] – persistent in db

oldest, newest = querydb()
extraold = fetch(before=oldest)
with db.transaction():
extranew = fetch(after=newest)
with db.transaction():

TODO in fact, even easier. if we only had after (assuming we could use 0 timestamp), then

newest = querydb() # always assumes
if newest is None:
newest = 0
extranew = fetch(after=newest)
with db.transaction():

the question is – what's fundamentally wrong with 'before' api that makes it so hard? am I onto something deeper?

# downside is that it's easy to miss errors?

# returning Union[Result, Exception]

yield in two places in code: splitting iterator by predicate [[ideas]] [[python]] [[yield]]

yield into failed
return passed, failed

not sure if that's very self consistent…
e.g. when we iterate over returned passed – how to iteratoe over failed as well
although could just treat
but how to transform this syntactically?

wonder if it can be rewritten with coroutines

[2019-12-24] similar idea: groupby fully on iterators

if last is not None:

last = None

for i in it:
if last is not None and key(last) != key(i):
yield i into group
last = i
'return' groups # more like yield from?

items = [1, 1, 1, 2, 2, 3, 5, 5, 5, 4, 4, 4, 2]

[2020-04-27] Riot | Malleable Systems Collective [[totweet]]

The physical objects around us have aspects, e.g. size, weight, temperature, fragility, stiffness.
They are very macroscopic, continuous and stable properties, so easy to experiment with and reason about.
That's also why it is somewhat flexible and possible combine and use in novel ways.

hmm so I guess your body could be 109m long and it wouldn't matter because you can only see past signals anyway (and you'll cross the event horizon faster?) basically your body is your lightcone, so the side doesn't matter, and the mind is pointlike (in GR you either have the same observer, or different, and it's kind of discrete in that sense)

I wonder what it means for a distributed system of neurons as it's passing through the events horizon though? Although it'll have a local update limit (irrelevant to speed of light, more of signal propagation rate), wonder what it would sense
